The objective of this study was to identify the musculoskeletal co-morbidities of neck pain of myofascial origin among IT professionals.
A retrospective report analysis of 5357 IT professionals from various IT companies in India was conducted. Demographic details, type and intensity of the musculoskeletal problems, employee feedbacks on status of musculoskeletal health and physician’s diagnosis were analysed. Descriptive statistics were used to describe the age, gender, body area affected and nature of work. Chi square test was used to find the association between musculoskeletal co-morbidities and myofascial neck pain (MNP).
The study participants were predominantly males (71%). 41% of the population used laptops, 35% desktops and 24% both. Neck pain was the commonest reported symptom, followed by low back, shoulder and arm pain respectively. Statistical analysis also revealed that low back pain and shoulder pain, had a significant association with neck pain. Further analysis revealed that there was a significant association between the presence of MNP and thoracic outlet syndrome (p < 0.001) and fibromyalgia syndrome (p < 0.001). Other than the listed co-morbidities, eye strain was also found to be associated with MNP.
Low back pain and shoulder pain was found to be co morbid symptoms noted among IT professionals with MNP. Thoracic outlet syndrome and fibromyalgia were found to be the most commonly associated disorders with MNP among IT professionals.
- Neck pain
- Low back pain
- Thoracic outlet syndrome
- Myofascial pain syndrome
Musculoskeletal pain is common among IT professionals ,. Low back pain is the most common musculoskeletal complaint in the general population, with, in the Netherlands, a one year prevalence rate of 44% . The same national study showed a one year prevalence of 31% for neck complaints, 30% for shoulder complaints, 11% for elbow complaints, and 18% for complaints of the wrist . Various risk factors have been proposed for work related musculoskeletal disorders (WRMSD), but its etiology is still unclear. A new approach to find out the etiology of such disorders is the consideration of co-morbidity ,. Co-morbidity can be defined as the presence of one or more disorders (or diseases) in addition to a primary disease or disorder, or the effect of such additional disorders or diseases. The underlying basis for such studies is that if there is a presence of two or more diseases simultaneously, they may have a common origin. Reporting of one musculoskeletal complaint along with other musculoskeletal co-morbidity is common in literature. Neck pain is one of the most common musculoskeletal disorders (MSD) in the general population, with a 1-year point prevalence of approximately one-third of adults . Co-morbidity studies of MSD have been the third most frequently studied index disease (13%) among all other diseases. A high prevalence of neck pain has been reported among IT professionals. A study carried out by Sharan et al. found that along with neck pain (64.9%), low back pain (56.5%), shoulder pain (42.1%), arm pain (34.5%) and wrist pain (19.8%) were prevalent among the IT professionals in India . It was also reported that myofascial pain syndrome (MPS) was the commonest diagnosis in subjects with neck pain . Given such a high prevalence it is not surprising that a subject suffering from neck pain may often experience other musculoskeletal complaints. Previous studies have found that presence of a MSD other than neck pain, mostly work related or non specific, is a predictor of poor prognosis in neck pain –. Keeping that in mind a study was conducted to identify the musculoskeletal co-morbidities of myofascial neck pain (MNP) among IT professionals in India.
Study design, setting and population
A retrospective report analysis was conducted in which records of 6563 employees from registers of on-site occupational health clinics situated in different IT companies at three cities (Bangalore, Delhi and Hyderabad) in India were analysed. All the employees engaged in the use of computers (laptop, desktop or both) as a part of their regular work, and visited these on-site clinics for treatment of different MSD. Informed consent was obtained from all the participants before evaluation.
Study duration and data collection
All the reports from the year 2005 to 2011 were reviewed. Reports included demographic data, chief complaints, diagnosis, treatment given and subjective feedbacks. Demographic data in the reports included age, gender, duration of computer usage per day, and the type of use (Laptop/Desktop/Both). Data regarding type and severity of the musculoskeletal problems were collected from the reports of an orthopaedic and rehabilitation physician who visited all the on-site clinics. A single orthopaedic and rehabilitation physician performed the evaluation and diagnosis of WRMSD’s was made based on time rule. MPS was diagnosed based on Simon’s criteria . Employee feedbacks were also used for evaluating the status of their musculoskeletal health.
Descriptive statistics like mean, percentage and frequency were used to describe the age, gender, body area affected and nature of work. Chi square test was used to find the association between musculoskeletal co-morbidities and neck pain. The data were analysed using statistical software SPSS version 17.0.

TOS was found to be comorbid with MNP in both males (40.10%) and females (45.23%). On the other hand co-morbidity of FMS with MNP was found to be 16.61% for males and 22.80% for females respectively. Further analysis revealed that there was a significant association between MNP and TOS (p < 0.001) and FMS (p < 0.001). Various variables and its correlation with TOS and FMS are presented in Table 2.
Musculoskeletal co-morbidity is common in the field of occupational health. The addition of co-morbidities to various WRMSD leads to an increment in the absenteeism –. The co-morbidity of neck and low back pain, reported as 68%, affected health care utilisation and absenteeism ,. In another study confounding co-morbidity of low back pain and neck pain was reported and low back pain was considered as predictor of neck pain ,. The present study also revealed a similar result.
The present study revealed that low back pain, shoulder pain, forearm and wrist pain were co morbid with MNP among the IT professionals in India. There was a strong correlation between these symptoms which was suggestive of awkward posture as a risk factor for WRMSD. Eye strain was found to be the other common co morbid symptom noted among IT professionals with MNP. The study suggested the presence of symptoms in multiple regions with longer working hours, in both genders irrespective of their age and type of computer usage. Low back pain as a co-morbid symptom of neck pain was more common in younger age groups and in subjects who worked for longer hours. Forearm and wrist pain as a co-morbid symptom of neck pain was more common in older age groups and in subjects who worked for longer hours. This is suggestive of static loading as a possible risk factor for low back pain and abnormal posture as a possible risk factor for wrist pain.
Co-morbidity of neck pain and FMS is well reported in the literature ,. The present study also corroborated these findings. It has been reported that psychological symptoms were higher among the co-morbid patients . A study on the mental-physical co-morbidity and its relation with disability suggested that with increasing number of co-morbidities the psychosocial risk increased which ultimately led to reduced productivity and poorer health .
Among workers with low back pain, subjects with high pain intensity or disabling low back pain are more likely to have musculoskeletal co-morbidity . The present study involving IT professionals showed a high prevalence of other musculoskeletal co-morbidities with neck pain. For occupational health practitioners the finding of a high prevalence of co-morbidities is important to consider when implementing workplace interventions aimed at the reduction of specific musculoskeletal complaints, since the controls for one musculoskeletal complaint may impact adversely on another musculoskeletal complaint .
Myofascial pain syndrome was found to be the commonest cause for neck pain. TOS and FMS were the commonest disorders associated with MNP among the same population. TOS as a co morbidity of MNP was more common in older age groups and in subjects who worked for longer hours, which is suggestive of MNP being a predictor of TOS. It is possible that early detection and treatment of MNP could prevent occurrence of TOS. Further research is recommended to identify the root cause of such co-morbidities.
